Bad music experience heared from IVR

Hi,
We have tried a lot of mp3 music file, and it is all good in computer. But it is always scratchy once upload to ivr server and listened from phone.
It seams that plum server has done a high compression to our music file.
The background of music is always scratchy, that usually needs a high quality.
We have tried sevaral format as the document mentioned
* 8 kHz 16-bit linear PCM headerless (*.l16)
* 8 kHz 8-bit µ-law encoded headerless (*.ul)
* 8 kHz 8-bit a-law encoded headerless (*.al)
* 8 kHz 16-bit linear PCM WAV (*.wav)
* 8 kHz 8-bit µ-law WAV (*.wav)
* 8 kHz 8-bit a-law WAV (*.wav)
* MP3 (*.mp3) - Note: If the audio file is poorly encoded, the mp3 will not work.
So far we can not get a good experience.
